It's called Classless Inter- Domain Routing (CIDR). In this case the /29 says only 8 usable addresses. This is actually a more efficient way of describing networks from the point of conserving IP addresses and you'll see it a lot. A /32 really refers to a unique IP address. Here's a nifty little chart that breaks it down better. CIDR Block Prefix # Equivalent Class C # of Host Addresses /32 1/256th of a Class C 1 host /31 1/128th of a Class C2 hosts /30 1/64th of a Class C 4 hosts 129 1/32th of a Class C 8 hosts /28 1/16th of a Class C 16 hosts /27 1/8th of a Class C 32 hosts 126 1/4th of a Class C 64 hosts /25 1/2 of a Class C 128 hosts /24 1 Class C256 hosts /23 2 Class C 512 hosts 1224 Class C 1,024 hosts /21 8 Class C2,04 bacte 10:00 my.cs.coloradotech.edu /24 1 Class C 256 hosts /23 2 Class C 512 hosts /22 4 Class C 1,024 hosts 121 8 Class C 2,048 hosts /2016 Class C 4,096 hosts /19 32 Class C 8,192 hosts 6. This will scan a single IP address, just change the IP to the one you want. 1. Start WireShark 1. nmap -SP-PA (2 points) 1. What is the -PA option (2 points) but nmap -SP-PA
